What product type is required to perform a radiometric conversion using the Radar Conversions tool?
Radiometric conversion is possible for detected products only. In a detected product, calibration constants are provided in the header of the original data and the image data was precalibrated by an SAR processor. For RADARSAT and ASF images, a look-angle dependant correction is implemented in the Radiometric conversion tool. Typical output values in Decibel units range from -20 dB to +5 dB.
